BUBBLE-PIPE.

Application filed June 15,

T 0 all who-m it may concern:

Be it known that I, JOHN E. DORRIS, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented new and useful Improvements in Bubble-Pipes, of which thefollowing is a specification.

This invent-ion relates to a soap bubble pipe by which a large number ofbubbles can be blown from a single charge.

It is the object of this invention to produce a pipe of this characterwhich is simple and compact in construction, which can be manufacturedat a moderate cost, and which can be conveniently carried in ones pocketwithout danger of its leaking.

A further object of the invention is to provide ellicientand reliablemeans for intermittently feeding the soapy-water from the main reservoirto the supplemental or exit chamber.

In the accompanying drawings; Figure 1 is a vertical longitudinalsection of one form of my improvement. Figs. 2 and 3 are horizontalsections thereof on the correspondingly numbered lines in Fig. 1. Fig.4: is a view similar to Fig. 1, showing a modified construction. Fig. 5is a horizontal section on line 5-5, Fig. 4.

Similar characters of referenceindicate corresponding parts throughoutthe several views.

In the embodiment of the invention shown in Figs. 1-3, the bubble pipecomprises a tubular body 10, preferably of cigar-shaped form andconstructed of two half sections made of wood, clay or similar materialand permanently secured together with glue, cement or other adhesive.This body is provided with a mouth piece or portion 11 at its uppercontracted end and an exit or outlet passage 12 preferably ofupwardly-tapering form, at its other end. Arranged in the upper portionof this body and extending the major part of its length is a mainreservoir or chamber 13 for containing soapy-water, while in the lowerportion thereof is a supplemental chamber 1% which is adapted tointermittently receive a small quantity of the soapy water from the mainreservoir for blowing a small number of bubbles. The main reservoir andsupplemental chamber are separated or divided by a diaphragm orpartition 15 which is provided with a connecting passage16. ThisSpecification of Letters Patent.

passage is controlled by a suitable gravity valve 17, constructed oflead or similar material, which is adapted to open upwardly toward themouth piece 11. Thestem 18 of this valve extends vertically downwardthrough the passage 16' and is provided at lts lower end with a head 19which serves as a stop for limiting the opening movement of said valve.

Connecting the mouth piece-11 of the pipe with the supplemental chamber14.- and preferably extending through the main reservoir 13 anddiaphragm 15 is an air blowing passage or tube 20 which may beconstructted of thin metal tubing, glass or similar maeria To permit offilling the main reservoir with soapy water, it is provided in its upperend with an opening 21 closed by a suitable plug 22.

After filling the reservoir 13, the user shakes. the pipe smartly toopen the valve 17 and allow a small quantity of the soapy Water to enterthe supplemental chamber 14 through the passage 16 in the diaphragm.Upon blowing through the air tube 20, the film, extending over the'lowerend of the exit passage 12 will be formed into a bubble, and uponshaking it off by a slight jerk of the pipe to one side, and blowingagain, another bubble will be formed, and so on until the supplementalchamber is exhausted, when the pipe is again shaken smartly, to allowthe gravity valve to open and admit another supply to said chamber.

In the modification shown in Figs. 4 and 5, the body of the pipe iscylindrical in shape, and comprises a tube 25 of glass, wood or othermaterial, being open at either end and having a mouth piece 26 securedin its upper end and an exit or outlet plug 27 secured in its lower end.The tube is divided by a diaphragm 28 into a main reservoir 29 and asupplemental chamber 30, the passage in the diaphragm being controlledby a valve 17 identical with that of the preferred construction. Themouth piece is connected with the supplemental chamber by an air tube31. The members 26, 27 and 28 may be made of wood or similar materialand suitably held in the glass tube 25.

As a whole, this bubble pipe is exceedingly simple in construction, andbeing composed of few parts, can be manufactured at a low cost.Furthermore, it is compact and non-leakable, rendering it capable ofbeing carried in ones pocket.

I claim as my invention:

1. A soap bubble pipe comprising a main reservoir for soapy water, asupplemental chamber disposed in substantial alinement with said mainreservoir and having an outlet passage, a diaphragm separating saidreservoir from said supplemental chamber and having a passage thereinconnecting the latter and said reservoir, a gravity valve controllingsaid passage, and an air tube extending through said reservoir and com-Inunicating with said supplemental chamber.

2. A soap bubble pipe comprising a tubular body having a mouthpiece atone end and an outlet passage at its other end, a main reservoir forsoapy water arranged in the upper portion of said body, a supplementalchamber arranged in the lower portion of said body and communicatingwith said outlet passage, a diaphragm dividing said reservoir and saidsupplemental chamber and having a passage therein connecting the latterand said reservoir, a gravity valve controlling said passage, and an airtube connecting said mouthpiece with said supplemental chamber.

'3. A soap bubble pipe comprising a tubular body having a mouthpiece atone end and an outlet passage at its other end, a main reservoir forsoapywaterarranged in the upper portion of said body and extending themajor portion of its length, a supplemental chamber arranged in thelower portion of said body and communicating with said outlet passage, adiaphragm dividing said reservoir and said supplemental chamber andhaving passages therein, a gravity valve controlling oneof sai-dpassages, and an air tube connecting said mouthpiece with saidsupplemental chamber and having its lower end arranged in the otherpassage or" said diaphragm.

4;. A soap bubble pipe comprising a main reservoir for soapy water, asupplemental chamber arranged directly below said reservoir and havingan exit passage, a diaphragm dividing the latter andsaid supplementalchamber and provided with a passage, a gravity valve controlling saidpassage and opening toward said reservoir, a stop for limiting theopening movement of said valve, an air passage extending centrallythrough said reservoir and communicating with said supplemental chamber,and a filling opening-arranged in the upper portion of said reservoir.
